Abstract

We predict strong interface multiferroicity at bccFe/BiFeO3(001) heterointerfaces by using first-principles calculations. For the identified stable atomic structure, we quantify the changes in the orientation of the magnetic moments of bcc Fe due to the reversal of the electric polarization of BiFeO3. By determining the magnetoelectric tensor, we find that the magnetoelectric coupling of the present ferromagnetic-multiferroic interface is an order of magnitude larger than that of a ferromagnetic-ferroelectric interface, bccFe/BaTiO3(001).
